The Mavic Mini combo pack I bought included a dome charging stand, which looks a lot cooler than it is practical. It's nice to keep the drone clean, but charging one battery at a time was tiring. This became evident when I took a sunset flight with a friend and at 10pm started charging my 3 batteries. I had to wake up 2 or 3 times in the middle of the night to change the batteries so they were fully charged to fly the next morning. Another problem is that batteries sometimes fail while charging and can leak or explode. Due to the constant charging of the batteries in the drone, there is a risk of damage or destruction in the event of a malfunction. This two-way charging accessory is value for money thanks to the build quality and the fact that it intelligently charges your batteries and remote control in one device. . The charger is almost entirely made of plastic, but feels smooth and of good quality. The batteries fit satisfactorily into the charging slots and snap into place with a reassuring click. What a lot of people probably don't understand is the charging logic, that the batteries are not charged all at once, but sequentially, starting with the fullest charge. complete to a minimum. As you place your batteries in each battery, the state of charge is displayed with individual gauges for each battery. The reason is so you can fly as fast as possible, so the most full battery will be charged first. If you have a charger that is certified for fast charging (5V, 3 amps), you can charge your batteries quickly. I can charge 3 batteries from an empty one in less than 3 hours with the remote control. I haven't timed it, but it's always ready when I want to fly. Batteries or charger do not seem to heat up significantly. The "two-way" feature of this charging hub is that it doubles as a battery pack, which is pretty handy when you're out and about without access to a power source and want to charge your phone or other device. The USB port acts as a power source with your batteries. I don't actually use this feature, but it's nice that DJI made this charger multifunctional. , which is the norm, as with all of their other products. You must have your own AC/USB power adapter, which must be powerful to get the best charging speed. Also, LED lights can be a bit bright, especially when installed in the bedroom. There is no way to turn off or dim the lights.
